"We have a WP-Pro mailing list which you are encouraged to use.
Just FYI, it's not that easy to use. I've joined, tried to email to it and every single time, I'm notified that it went "unprocessed"
Not sure what I am doing wrong, but after about 10 tried, I just gave up... since it doesn't offer any possible reasons WHY such a thing is happening.
I've contacted the list owner at least once with no response.
